Yesterday, following the slide in stocks, we looked at some charts on stocks, gold and the dollar. We talked about the media and Wall Street’s need to fit price action to a story. And we asked if the story did indeed warrant fitting it to the price action. Was a crisis beginning or just a correction for stocks?The answer: It still looks like a market that values fiscal stimulus and structural change over political mudslinging and scandal. For stocks, the news may have been the catalyst to start a healthy technical correction.

Today, the market behavior appears to support that view.

Now, with the idea that a technical correction is (I think) underway for stocks, and maybe for months, until we get a better handle on policy action, remember this: a correction in stocks is a buying opportunity.

Major asset classes, over time, will rise (stocks, bonds, real estate). The value of these core assets will grow faster than the value of cash.

That comes with one simple assumption. The world, over time, will improve, will grow and will be a better and more efficient place to live than it was before. If that assumption turned out to be wrong, we have a lot more to worry about than the value of our stock portfolio.

With that said, as an average investor that is not leveraged, dips in stocks, particularly U.S. stocks—the largest economy in the world, with the deepest financial markets—should be bought, because in the simplest terms, over time, the broad stock market has an upward sloping trajectory. Instead, dips in stocks tend to create fear, and fear creates selling, at precisely the time we should be buying.

With this in mind, we’ve had a brief dip of about 4% in stocks within the “Trump trend” (the post–election rise in stocks). A typical correction is around 10%. But strong bull markets tend to have shallow retracements. A 6%–10% correction in stocks would take us back to the 200–day moving average (minimum), and maybe as low as 2,200 in the S&P 500.
